SMARC-sAMX6i / Introduction
2 Introduction
2.1 Product Description
The small-sized SMARC™ Module with Freescale i.MX6 processor offers a wide range of processor scalability with single,
dual and quadcore processors. The X86 alike interfacing of SMARC-sAMX6i allows an easy integration in any kind of
application.
2.2 SMARC™ Computer-on-Modules
The SMARC™ standard was developed especially for new modules with ARM- and SOC-processors and is characterized by
the extremely flat build of its form factor. It is based on the MXM 3.0 connector with 314 pins and a construction height of
just 4.3 millimeters and it thus allows robust and flatly constructed designs with a cost-effective card edge connector. The
connector is also available in a shock- and vibration-resistant version for rough environmental conditions. Furthermore,
the standard integrates dedicated interfaces for the latest ARM and SOC processors which not only means LVDS, 24-bit
RGB and HDMI support but also support of embedded DisplayPort for future designs. In addition, and for the first time,
dedicated camera interfaces are being incorporated into a COM standard. OEMs profit from minimized design effort and
bill of material costs. SMARC™ defines two different module sizes in order to offer a high level of flexibility regarding
different mechanical requirements: a short modules measuring 82 mm x 50 mm and a full-size module measuring 82 mm x
80 mm.
SMARC™ is the low-power embedded architecture platform for computer-on-modules based on ARM technology.
» Creating mobile, embedded, connected solutions
» Scalable building blocks
» Optimized pin-out definition for ARM technology
» Ultra low-power, low-profile solutions
» Constructed to withstand harsh industrial environments

SMARC-sAMX6i / Product Specification
3.6 Power Control
Power Supply
The SMARC-sAMX6i supports a power input from 3.0-5,25V. The supply voltage is applied through the VCC pins (VCC) of the
module connector.
Power Button (PWR_BTN#)
The power button (Pin P128) is available through the module connector described in the pinout list. To start the module
via Power Button the PWRBTN# signal must be at least 50ms (50ms ≤ t < 4s, typical 400ms) at low level (Power Button
Event).
Pressing the power button for at least 4seconds will turn off power to the module (Power Button Override).
CB_POWER_BAD#
The SMARC-sAMX6i provides an external input for a Carrier Board Power Bad signal (Pin S150). The implementation of this
subsystem complies with the COM Express® Specification. CB_POWER_BAD# is internally pulled up to 3.3V and must be
high level to power on the module.
Reset Button (RST_CB_IN#)
The reset button (Pin P127) is available through the module connector described in the pinout list. The module will stay in
reset as long as RST_CB_IN# is grounded.
3.7 Power Consumption
Following data provides power consumption measurements of single modules with i.MX6 solo (51003-0540-08-1) and
i.MX6 quad (51003-1040-08-4).
processor linux shell mem test
i.MX6 solo 2.46W 3.47W
i.MX6 quad 2.87W 4.52W
This might not be the maximum load a module can have, but due to the lack of standardized stress test software for ARM
processors this data cannot be provided.

SMARC-sAMX6i / Product Specification
3.10 MTBF
The following MTBF (Mean Time Before Failure) values were calculated using a combination of manufacturer’s test data, if
the data was available, and the Telcordia (Bellcore) issue 2 calculation for the remaining parts.
The calculation method used is “Telcordia Method 1 Case 3” in a ground benign, controlled environment (GB,GC). This
particular method takes into account varying temperature and stress data and the system is assumed to have not been
burned in.
Other environmental stresses (extreme altitude, vibration, salt water exposure, etc) lower MTBF values.
System MTBF (hours): 209423 @ 40°C
Fans usually shipped with Kontron Europe GmbH products have 50,000-hour typical
operating life. The above estimates assume no fan, but a passive heat sinking arrangement
Estimated RTC battery life (as opposed to battery failures) is not accounted for in the above
figures and need to be considered separately. Battery life depends on both temperature
and operating conditions. When the Kontron unit has external power; the only battery
drain is from leakage paths.

==>
5.4.2 md5sum
Creates or checks the md5 message digest over a memory area
Syntax
md5sum <data-address> <length> [<cksum-address>]
-md5sum
command
-<data-address>
parameter: hexadecimal
start address of memory area
-<length>
parameter: hexadecimal
length of memory area
-<chksum-address>
parameter: hexadecimal
If present: compares the calculated md5 message digest with the md5 message
digest available at this address.
If absent: calculates the md5 message digest over the specified memor y range and
prints it to the console.
Description
his command is used to create or check the md5 message digest over a memory area.
If the optional 3rd parameter <checksum-address> is omitted, the md5 message digest is calculated over the specified
33
SMARC-sAMX6i / Bootloader Operation
memory range and printed to the console.
If the optional 3rd parameter <cksum-address> is specified, the md5 message digest is calculated over the specified
memory range and compared with the md5 message digest at <cksum-address>. If the digest is identical, the command
returns 0; if the digests do not match, a value other than zero is returned. When a comparison is made, nothing is printed
to the console since this usage of the command is meant to be used within scripts.
The md5 message digest at <cksum-address> may be specified in ASCII or binary format.
Usage
Calculate an md5 message digest: Check the md5 message digest of a file previously loaded to 100000 with a size of 80000
and its md5 message digest loaded to 10000 in a script
=> setenv check_crc “if md5sum 100000 80000 10000; then echo ‘md5 message
digest OK’; else echo ‘md5 message digest BAD’; fi”
=>run check_crc
md5 message digest OK

5.5 U-Boot Access and Startup
Communication with U-Boot is achieved via a serial console configured for 115200 baud, 8N1, no hardware handshake.
Initially, U-Boot executes the commands defined in the environment variable “preboot”. Then, if not otherwise
interrupted, U-Boot pauses for the time defined in the environment variable “bootdelay” and then executes the
statements stored in the environment variable “bootcmd”. To gain access to the U-Boot command prompt, type in any
single character during the boot delay time.
If required, the boot delay function can be configured in such a way that even when the boot delay is set to “0” to have
characters, which are sent over the serial interface prior to the boot wait time, be recognized to allow operator
intervention in the boot process.
5.6 Environment
The Environment is stored in the same flash as U-Boot, usually in the last sector. This provides the possibility to update UBoot without changing the Environment. The environment can be modified by the user with the typical commands of the
‘env’ command group: ‘setenv’, ‘editenv’, ‘printenv’ and ‘saveenv’.
Furthermore, if a larger number of boards require updating the environment can be updated by a script, loaded from the
SD card, USB or SATA device, or a network.
A typical user modification would be to set the variable ‘bootcmd’ so that the user’s OS will boot automatically.

SMARC-sAMX6i / Bootloader Operation
5.7 Working with U-Boot
5.7.1 General Operation
Most operations are carried out using the main memory as an intermediate step. It is not possible, for example, to boot a
kernel image directly from a tftp server. Instead, the kernel image is first loaded to memory and then booted from there
with another command.
The same is true when writing new contents to the SPI boot flashes.
This concept is very flexible since it separates the commands which handle the loading of data from the commands that
carry out actions like booting or programming flash devices.
5.7.2 Using the Network
U-Boot provides support for the onboard Ethernet interfaces for transferring files from a file server.
To be able to transfer files from a tftp server to a module, the module’s IP address (environment variable ‘ipaddr’) and
the IP address of the server must be set (environment variable ‘serverip’). Alternatively, it is possible to use the ‘dhcp’ or
‘bootp’ commands.
They can be set using the ‘setenv’ command. Please note, that these settings are lost after a reset. To retain the
environment permanently, use the command ‘saveenv’, which saves the complete environment to flash.
To transfer a file from a tftp server to memory, the ‘tftpboot’ command is used, for example:
> tftpboot 10800000 filename
5.7.3 Using SD Cards and onboard eMMC device
SD Cards are supported (read only) with the ‘ext2’ or ‘fat’ file system.
In both cases, the card must be rescanned first.
> mmc rescan 0
After that, the contents can be verified with:
> ext2ls mmc 0
in case of the ext2 file system, or
> fatls mmc 0
in case of the fat file system.
To load a file into memory the commands ‘ext2load’ or ‘fatload’ can be used, for example:
> ext2load mmc 0 10800000 kernel.bin
which loads the file ‘kernel.bin’ from the SD card to memory address 0x10800000.
5.8 Bootloader Update
Updating the bootloader of SMARC-sAMX6i can be done by using the already implemented update script.
5.8.1 Downloading the bootloader
Please download the regarding bootloader from Kontron's Customer Section.
5.8.2 Updating via TFTP Server
If you have a development setup with TFT Server please unpack the downloaded archive to your server's folder. There
should be a folder named “update_smx6”.
36
SMARC-sAMX6i / Bootloader Operation
Restoring Environment
If your U-Boot envirenment is misconfigured you can restore it with following commands:
> tftp 10800000 amx6-(correct name of the environment).txt
> env import –d –t 10800000 $filesize
> saveenv
> reset
Running Update Script
To start the update script please enter following command:
> run netupdate
With the option ”-d” of the env import command you will lose all your previous made
environmental settings.
5.8.3 Updating via USB Stick
Unpack the downloaded archive to a USB stick's first partition. There should be a folder named “update_smx6”.
Please enter following command:
> run update
5.9 Bootlogo
A Kontron Bootlogo can be shown on an LVDS panel only. To control the bootlogo behaviour following commands can be
used:
> setenv panel LCD_WVGA@LVDS
Outputs the bootlogo on LVDS in panel resolution 800×480
> setenv panel LCD_WXGA@LVDS
Outputs the bootlogo on LVDS in panel resolution 1280×768
> setenv panel off
Disable LVDS output
> setenv panel
Outputs the bootlogo on LVDS in panel resolution 800×480 shipping default (variable unset)
To save the setting for the next boot, please save your environment with
> saveenv
The bootlogo can be not exchanged to another bitmap.
